Professional Wheel Alignment Gauge

For a bicycle wheel to perform properly and safely, it is important for the rim to be centered between the locknuts of the hub, or “dished." The WAG-4 is an accurate and versatile alignment gauge that provides a measurement of the dish in order to determine if adjustment is necessary. Compatible with virtually all road, mountain, BMX, and cruiser wheels.

The sliding spacer blocks of the WAG-4 offset the tool from the rim, allowing for accurate measurement even when the tire is still mounted on the wheel.
